Examples
Example #1 Mutex Locking and Unlocking
<?php/** You cannot use the "new" keyword, a Mutex is not a PHP object **/$mutex = Mutex::create();/** You can now lock the mutex in any context **/var_dump(Mutex::lock($mutex));/** It is invalid to attempt to destroy a locked Mutex **/var_dump(Mutex::unlock($mutex));/** Always destroy mutex you have created **/Mutex::destroy($mutex);?>
The above example will output:
bool(true) bool(true)
